When due to its serious pollution that is non-renewable, and being brought to environment using fossil fuel, given survival and development of mankind band
Severe challenge is carried out.Currently, the associated mechanisms of countries in the world all utilize reproducible green energy resource in active development.Wind energy conduct
Reproducible clean energy resource has abundant wind energy resources to make polar region wind generating technology especially in Arctic in arctic regions
As inquiring into the hot spot of research, and the trend as the following development and application in recent years.
If six state of ring Arctic be in it is coastal or be located at the Arctic Ocean, long-term wind speed is higher, year theoretical power generation, year technology
Exploitable deposit accounts for the 18.5% of Global Wind-energy resource, 17.2% respectively, and wind energy resources are abundant, have as global energy internet wind
The resources supplIes in electric base.Bering Sea, Chukchi Sea, the Branchian Sea, Greenland, Kara Sea are opposite suitable for Wind Power Generation.North
Polar region wind power technology can development capacity be 110.6 × 108kW, wherein 73.1 × 108kW of land, 37.5 × 108kW of marine site；Such as
Removal Greenland ice sheet thickness is more than the area of 10m, can develop installed capacity as 88.9 × 108kW, wherein land 51.4 ×
108kW, marine site are same as above.According to estimates with the relevant technologies progress, the following wind power resources utilization ability can further be promoted to 1000
×108kW。
But since aggravation is melted in global warming, arctic glacier in recent years, as a large amount of Melting Glacierss are broken, increase
The quantity on floating iceberg and small-sized ice body, also increases the collision probability of same offshore structures.Driving of the sea ice in wind and stream
Under, horizontal pushing pressure power is generated to the platform being in contact with it in leeward or downbeam.With the wind, the floating ice of stream drift, is touched with platform
Impact force is generated when hitting, and when floating ice is flowed through from the wind power generation platform side, cutting, abrasive action are generated to platform.Work as sea ice
When acting on platform, the elimination of ice force when being crushed with sea ice may cause the vibration of platform, when the frequency of this vibration
When close with the natural frequency of vibration of platform, caused resonance can result in platform and topple over.
The failure mode of ice raft mainly squeezes destruction, lateral deflection destruction, Longitudinal shear failure and bending failure.According to sea
It is found in the research of ice physico-mechanical properties, the bending strength of ice raft is significantly lower than compressive strength.If in water surface variation range
It is interior using the pile with inclined surface, then the failure mode of ice raft will be changed into breaking based on bending by destructions based on extruding
It is bad, thus it can greatly reduce the ice power acted on works by the change of ice raft failure mode.When ice raft and inclined-plane
When works acts on, the ice pressure acted on inclined-plane can be decomposed into the normal force perpendicular to inclined-plane and oblique point along inclined-plane
Power.Oblique component makes ice cube rise along inclined-plane.The vertical force that normal force decomposites makes ice sheet generate bending or shearing, decomposites
Horizontal force is then significantly smaller than the extruding force of straight wall cylinder more.It can be seen that italic structure is a kind of effective anti-ice pattern.
